How Viola saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Only the radar-estimated size surface resolved for Jun 13, 2026 — this storm produced no NEXRAD point detections over Viola, so there is one map to show, not two.
Where Jun 13, 2026 sits in Viola's hail record
This was Viola's 4th recorded hail day, arriving 12 days after the Jun 1, 2026 storm. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Viola at 0.75" — radar-estimated size aloft.
The Jun 13, 2026 convective day was bigger than Viola: the same system put hail over 587 other tracked cities, 167 of them in Kansas. Nearest: Milton (6 miles southwest, up to 0.75"); Clearwater (11 miles east, up to 0.75"); Norwich (11 miles west, up to 0.75").
These maps are stills from Viola's Jun 13, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
What people on the ground reported

What 0.75" hail means for Viola roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
What this storm is worth to a roofer
$3.5M
Potential roof exposure — 289 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 2, 2026.
